Narrative:
This experience occurred on the SADDE6 arrival into lax. After crossing the smo VOR at 7000 ft MSL we were given a vector of 070 degrees. Very light winds out of the east about 7kts at the time. At the time of the incident; as the pilot not flying; I was heads down making final adjustments to nav radios and FMS inputs. During this time; the captain called for my attention to check hydraulic pressures (his initial reaction was that we had a floating spoiler). By the time I looked up and over at him he had full control wheel deflection; left and right; with no aircraft response. Only after using asymmetric thrust with full control wheel deflection was he able to raise the wing back to level flight and regain control. Immediately following the control issue we queried socal approach as to the traffic we were following into lax. We were advised that there was a 737 in front of us (don't remember his distance); and also a A380 that was on 5 mile final.after much discussion between ourselves and neither one of us having ever experienced a wake encounter of that magnitude; our best professional opinion was that it was the wake of the A380 that we flew through that morning.
